Ca:P Ratio

In 6 experiments with 359 pigs weighing 30 to 110 kg different amounts of phosphorus were added to the diet as CaHPO4 in 3 or 4 steps of 0.75 g P/kg. All diets had a Ca:P ratio of +or- 1.3:1. Optimum results were obtained by addition of 0.75 g inorganic P with digestible P 1.6 to 1.8 g/kg DM. (Abstract retrieved from CAB Abstracts by CABI’s permission)

Vitamin D3 Supplementation

A diet based on field peas and barley can satisfy the mineral requirements of growing pigs provided that calcium is supplemented at least to the level of dietary phosphorus present, and that vitamin D3 supplementation is greater than Agricultural Research Council recommendations. Bone fragility and lameness observed in pigs on a low calcium-low vitamin D3 diet was overcome by increasing either of these components, and this was accompanied by increased metacarpal ash and femur breaking strength. A similar response could also be produced by increasing dietary phosphorus levels. Plasma calcium and phosphate concentrations were significantly influenced by changes in the dietary calcium/phosphorus ratio, whereas vitamin D3 changes had a minimal influence. Parathyroid activity appeared to reflect the plasma calcium concentration. There did not appear to be any relationship between plasma concentrations and bone fragility or lameness.In order to ensure adequate bone development in pigs offered a diet of plant origin, vitamin D3 supplementation and elevation of dietary calcium to the level of total phosphorus present is a minimum requirement.

P Cycle

The sustainability of animal production relies on the judicious use of phosphorus (P). Phosphate, the mined source of agricultural phosphorus supplements, is a non-renewable resource, but phosphorus is essential for animal growth, health, and well-being. P must be provided by efficient and sustainable means that minimize the phosphorus footprint of livestock production by developing precise assessment of the bioavailability of dietary P using robust models. About 60% of the phosphorus in an animal's body occurs in bone at a fixed ratio with calcium (Ca) and the rest is found in muscle. The P and Ca requirements must be estimated together; they cannot be dissociated. While precise assessment of P and Ca requirements is important for animal well-being, it can also help to mitigate the environmental effects of pig farming. These strategies refer to multicriteria approaches of modeling, efficient use of the new generations of phytase, depletion and repletion strategies to prime the animal to be more efficient, and finally combining these strategies into a precision feeding model that provides daily tailored diets for individuals. The industry will need to use strategies such as these to ensure a sustainable plant–animal–soil system and an efficient P cycle.

Abstract Sufficient supply of dietary phosphorus (P) is critical for maximizing muscle and bone growth of pigs. The objective was to compare standardized total tract digestible (STTD) P requirements of growing pigs determined in the experiments and those estimated using modeling approach. Fifty-two experiments in the literature that empirically determined P requirements of pigs were employed. The basis for the determination of P requirements were growth performance (average daily gain or gain to feed ratio; n = 34) and bone development (n = 23). Based on the STTD P in the feed ingredients provided in NRC (2012) and ingredient composition used in the experiments, P requirements presented as total P, available P, and true total tract digestible P were converted to STTD P requirements. To obtain STTD P requirements (g/d) suggested by NRC (2012) for grow-finishing pigs (body weight > 20 kg), mean body weight and sex indicated in the experiments were input into the NRC model. The statistical model for comparing the empirical data and the NRC requirements included the basis for determining P requirements in the experiments as a fixed variable and body weight as a random variable. To quantify the deviations between NRC STTD P requirement estimates and empirically determined STTD P requirements, mean percentage difference was calculated. The STTD P requirements empirically determined based on growth performance were greater than the NRC STTD P requirement estimates (5.89 vs. 4.61 g/d, SEM = 0.27; P < 0.001). Moreover, the bone development-based STTD P requirements were greater than the NRC STTD P requirement estimates (6.63 vs. 4.46 g/d, SEM = 0.42; P < 0.001). In conclusion, the standardized total tract digestible P requirements suggested by the NRC are less than the experimentally determined requirements.
